New bike/cassette teeth Sheering off!

[Hugo Stiglitz]

It's a 1x42 set up. Brand new bike and literally 1 ride. Two of the top ring teeth have sheered off. It's a SLX cassette.

In my view It's at the extreme of an acceptable chain line that's causing the issues.

With such cassettes costing upwards of £90 at the moment I'm not happy!

Bike is a Cube Race SL

Is my concern fair?

I've had some pretty nasty sounding, full gas shifts before but never snapped any teeth off a cassette. Suggest a trip to the bike shop or return of said cassette to the dealer for warranty replacement.

Erm, are you sure that they are not part of the design to aid shifting? Can you post a pic?

Just like the time I asked my LBS if a part of my cranks was missing as there was an empty space on the spindle on the drivetrain side...

1x(mahoosive) is always going to strain the biggest sprockets to within an inch of their life. The trick is to make sure that you’re engine is sufficient to rarely ( if ever ) need the dinner plate sprockets, and for as little time as possible. If you spend your entire time on the dinner plates, your going to get shark toothing.

With a properly setup 1x chainset, it shouldn't make a difference if you are on the biggest or the smallest cog in terms of chainline angle...

Most aren’t set up properly. You need to make sure you have spacers and shims in place to get the chain line optimal.
